Part of the 736 series, it cures at room temperature and achieves a tack-free surface in 17 minutes, with full cure in 24 hours. The operating temperature range spans -85 degrees F to 500 degrees F, making it suitable for exhaust systems, engine assemblies, and high-heat mechanical joints. It meets 21 CFR 177.2600 and MIL-A-46106 standards. Licensed HVAC technicians, pipefitters, and millwrights are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis sealant is used wherever a flexible, heat-resistant seal is required at metal-to-metal or metal-to-plastic joints. Typical applications include flange faces on HVAC ductwork, exhaust manifold gaskets, pump housings, and pipe connections that see elevated temperatures. The red color aids visual confirmation of sealant placement during assembly. It adheres to both metal and plastic substrates, broadening its use across a wide range of mechanical joint types found in commercial and industrial service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRTV silicone chemistry cures at room temperature with no external heat required\u003c\/li\u003e\n  \u003cli\u003eTack-free in 17 minutes, full cure in 24 hours for fast return to service\u003c\/li\u003e\n  \u003cli\u003eOperating range of -85 degrees F to 500 degrees F suits high-heat applications\u003c\/li\u003e\n  \u003cli\u003eMeets 21 CFR 177.2600 food-safe standard and MIL-A-46106 military specification\u003c\/li\u003e\n  \u003cli\u003eAdheres to metal and plastic substrates for versatile joint sealing\u003c\/li\u003e\n  \u003cli\u003eRed color provides visible confirmation of sealant coverage during assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for flange and gasket sealing applications on metal and plastic substrates across HVAC, industrial, and mechanical systems where a high-temperature RTV silicone sealant is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eApplied by HVAC technicians, pipefitters, or maintenance mechanics using a standard caulk gun fitted for 10.1 oz cartridges.
